Assassin's Creed Odyssey Isu Knowledge guide - Cache and Codex locations

In the final episode of the Fate of Atlantis DLC, the full power of the Staff of Hermes is revealed. To reach their full potential, the Eagle Bearer must find the sources of Isu knowledge to enable their sixth sense.

There are three levels - or sequences - that you can reach, with each new threshold allowing you access to more of the city of Atlantis.

You can get knowledge points from completing quests and side quests, or by finding the Keeper’s Insights hidden around the city. You main source of Knowledge however, are the Isu Caches and Codex found throughout Atlantis.

Here are all of the places I visited to raise my Isu Knowledge level to 3 without completing any of the DLC’s quests beyond the intro mission.
